From 2c3bf019fb06e411219f10feecbbe03941a6f97c Mon Sep 17 00:00:00 2001 From: Michel Lespinasse Date: Mon, 24 Jan 2022 17:43:53 -0800 Subject: [PATCH] FROMLIST: mmap locking API: mmap_lock_is_contended returns a bool Change mmap_lock_is_contended to return a bool value, rather than an int which the callers are then supposed to interpret as a bool. This is to ensure consistency with other mmap lock API functions (such as the trylock functions).
